Assume that for people under 50 years old, x has a distribution that is approximately normal, with mean ? = 51 and estimated standard deviation ? = 16. A result x < 40 is an indication of severe excess insulin, and medication is usually prescribed. b. What is the probability that x < 40?c. Repeat part (b) for n = 3 tests taken a week apart. d. Repeat part (b) for n = 5 tests taken a week apart.Assume the random variable x is normally distributed with mean p= 89 and standard deviation o = 5. Find the indicated probability.
